Was this purple foxglove intentionally planted against the orange lichen-encrusted wall? The effect of having all three of the secondary colours adjacent to one another is pleasing to me, whether it is by design or not.
The “friend or foe” Digitalis purpurea makes its second appearance on BPotD. For details on its medicinal and poisonous properties, please (re)visit that entry.
Purple foxglove is a biennial or short-lived perennial native to much of Europe, although it has naturalized in other temperate regions. The biennial life-cycle is often split into two phases (and this is true for Digitalis purpurea). After germination, growth in year one tends to be allocated to securing the space and nutrients needed for the next year; for purple foxglove and many other biennials, this is done by growing a series of concentric leaves with little stem length between the leaves. The effect is a basal rosette of leaves, which seems to both suppress any germination by competitors underneath its “canopy” and efficiently capture the immediately-available light resources. Second-year growth is more dedicated to reproduction. This is typically the development and growth of an upright stem bearing many flowers (and in many biennials, additional leaves). In the case of purple foxglove, this upright stem can be over 2m (6 ft.) in height. Seed production on an individual plant will number in the thousands.
